  Log Message:
  -----------
  [OpenMP] Propagate ALWAYS/DELETE/CLOSE map-type modifiers to mapper entries

Per OpenMP 6.0:281:34, when a map/motion clause uses a mapper modifier, any
map-type-modifying modifier on that clause applies to each map the declared
mapper specifies. Propagate the ALWAYS, DELETE, and CLOSE bits from the outer
clause's map type into every entry emitted by emitUserDefinedMapper, except
ATTACH entries (ATTACH|ALWAYS is reserved for attach(always), and the other
bits have no meaning for an ATTACH entry).

PRESENT is intentionally NOT propagated here: it requires distinguishing
pointee entries from the struct's own storage and is handled in a follow-up.
